Passing XML around in an app

[Dugr]

I'm writing a simple .NET 2.0 application and I'm writing a DLL for this app.
I want to pass an XML document into a public function of the dll and read
it's nodes and then pass the document around to other functions and subs in
the dll.

I'm getting lost with all the options.

What's the best way to do this. I would like to have an XMLDocument passed
into the function as opposed to a string that points to the location of the
file. Do I want to work with XMLDocument or is something else better suited
for this?

Is it easier to just have the Function accept a string and then turn the
string into a document that I can work with?

I will also need to create XML Documents (in memory only) and have my
function return those docs. What's the best way to do this.

Can someone please point me in the right direction?

Thanks for ANY help! I've been spining my wheels all day now.

..NET provides two in-memory XML stores you can use: XmlDocument and
XPathDocument. If you want editable in-memory XML store, use
XmlDocument, if you don't need editable one and XPath or XSLT are
involved, use XPathDocument.
